snappyHex fails in parallel (OF 1.5-dev)
Hello everybody
I can't get snappyHexMesh working in parallel with 2 processors, whereas the solvers do work fine.
I use 1.5-dev, compiled from sourceforge package. I have GCC4.4. I also tried GCC4.3.4 with the same results
The failure occurs during phase 2. Here is one of the error message :
Code:
Smoothing patch points ...
Smoothing iteration 0
Found 2331 non-mainfold point(s).
Scaling iteration 0
Moving mesh using diplacement scaling : min:1 max:1
Checking faces in error :
non-orthogonality > 80 degrees : 279

mpirun noticed that job rank 0 with PID 17941 on node linux0 exited on signal 15 (Terminated).
Sometimes, the message is slightly different :
